Composite Semaphore Flag for the Letter X - X-Ray

The Composite Semaphore Flag for X-Ray has a green background, because X is the 24th letter of the alphabet.  Reason being, 4 is coded to green and the ones digit value of a letter sets the colour.  As a reminder green is the fourth colour of the spectrum.  Also the stars represent the right-starboard arm of the Semaphore Signaler.
